Weighted Companion Cupcakes

First this is very easy to make but takes a lot of time so this is definitely a weekend project.  I was inspired by the Companion Cube cake instructable and I have been wanting to try out fondant for a while.  This is my first instructable so I would very much appreciate some pointers for future projects.  Now lets start with the baking

(Warning there will be little to no cake jokes)

These are the tools I used
-Wilton Silicone Brownie Square Baking mold(or your favorite baking 
-Serrated Knife
-Cutting tool for fondant (butter knife works well)
-Piping bags
-Plastic wrap
-Heart Sprinkles
-Wilton Food Writer Edible Color Markers
-Marble or plastic rolling pin
-Cupcake recipe(I used a sponge cake but any type of cake will do)
-Marshmallow Fondant( I made my own but you can buy it in packages as well)
-Shortening( found this helpful when the fondant became to tough to work with)

Bake your chosen cake recipe. (take off about 5 minutes on the bake time or your cubecakes will get burnt).  I found that I made less of a mess by piping the batter into the mold. Make sure that the batter almost comes to the edge of the molds so that it over flows a little while it rises in the oven.  You will see why in the next step

After you remove the cubecakes from the oven and let cool for 5-10 minutes cut off the top that has risen over the top of the mold so you get a nice brick o'cake.  You should have an even number to stack on top of each other so you make little cubes.

Roll out your fondant to about an 1/8".  Knead in about 1/4 teaspoon of shorting if it becomes to hard to work with or sticks to the rolling pin.  I made mine from a recipe but it was a lot of work and was kind of messy.  If I did it again I would either buy it or use a standing mixer.  

Now time to cut out the outside of your cube  Cut out a small cross in the fondant and measure with a cube to get the approximate dimensions.  Drape the fondant over the cubecake and pinch the edges of to fondant so it seals and create a cube-like shape.  This is pretty easy to do but takes a while.  Don't let it set too long because it will dry out and we want to add a few more things to it.

To make the corners cut out 3 small triangles and pinch them into a tetrahedron(without a bottom) and stick it to the cube.  
Then add a small square of fondant in the between the corners.
Lastly make a small sphere and smush(very technical term) it to the face of the cube 

Repeat until all edges, corners, and faces have been done.

Last but not least add your heart sprinkle to the center of all the sides of the cubecake and you can also add lines of dye with the markers if you would like.  

Hooray you made your first cubecake now only 11 more to go.  
Hope you had fun.
